Recently, bipolar host materials have attracted considerable attention because they can achieve balanced charge injection/transport in phosphorescent organic LEDs (PhOLEDs) and consequently obtain excellent device performance. Two bipolar host materials, namely, 3-(4,6-diphenyl-1,3,5-triazin-2-yl)-9-phenyl-9H-carbazole (DPTPCz) and 3-(4,6-diphenoxy-1,3,5-triazin-2-yl)-9-phenyl-9H-carbazole (DPOTPCz), were designed, synthesized, and characterized. With high triplet energy levels of 2.78 and 2.86 eV for DPTPCz and DPOTPCz, resp., 2 compounds are considered promising bipolar host materials for PhOLEDs. Blue and green PhOLEDs based on these 2 new compounds show excellent performances. The phosphorescent devices based on DPTPCz exhibit maximum external quantum efficiencies of 14.4% (for blue device) and 21.2% (for green device), and maintain high efficiencies of 11.9% and 20.0% even at a high luminance of 10,000 cd m-2.
